However I don't know how to do. Anyone who know the way to switch KDE to GNOME in Suse, please show me. Thanks in advance!

1)YaST>Software management>View>Patterns
2)Then Install both Gnome patterns.
3)When you next log in, go down to the left and select the Gnome desktop before you log in. You will always to logged in to the last desktop you used; so you only need to change this setting when you wish to swap to the other desktop.
